Self-cleaning membrane will shield sensors from immune responses

An implantable sensor that allows diabetics to more effectively monitor their blood-sugar levels is a step closer to reality, thanks to a researcher at Texas A&M University who is developing technology aimed at enabling these sensors to remain functional in the body for an extended period of time.

Dr. Melissa Grunlan, associate professor in the Department of Biomedical Engineering, is developing a “self-cleaning” membrane that envelops an implanted glucose sensor, shielding it from the body’s immune response that would otherwise render it nonfunctional.
